When a panel needs upgrading
Breakers that trip often, a fuse box, no open slots, or a new heat pump, EV charger or range are the common reasons. HomeAdvisor notes many older homes have only 60 amp service. An electrician runs a load calculation to decide the size.
Permits and patching
HomeAdvisor says permits and drywall repairs add $150 to $300. If the utility's service drop or the meter base has to change, the work and the timeline grow. Fixr lists replacing a panel at $1,000 to $3,500 and upgrading at $1,500 to $5,000.
